ATTACH ING GLAMR.

Application filed April 18, 1922. Serial No. 554,490.

0 hangers for clamps for trolley wires in electric railway systems employed in mines.

My object is to simplify and improve the existing art by producing a device of this character which can be easily, quickly and securely attached to the I beams that provide supports for such clamps,

The foregoing, and other objects wh ch will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and operative association of parts, such as is disclosed by the drawings which accompany and which form part of this specification.

In the drawings Figure 1 is an elevation of the improvement in app-lied position.

Figure 2 is a sectional view on the line 22 of Figure 1.

Referring now to the drawings in detail, the numeral 1 designates an Ibeam, such as is commonly employed for clamps for trolley wires in mines.

The clamp includes the hell 2 that carries the swivelly connected clamping jaws 3 which engage the wire 4. The opposite end of the bell has a threaded bore in which is screwed the shank portion 5 of one of the jaws 6 of my improvement.

Lbeam 1, a second jaw 7 being arranged over the opposite flange. This aw 7 is also provided with a threaded shank 8, but the supporting The jaw 6 is arranged over one of the flanges of the same is arranged substantially parallel with the jaw proper, and not right angularly with respect thereto, as is the shank 5 of the jaw 6. The shank 5, at its juncture, or slightly below its uncture with the jaw 6 is provided with around opening 9 through which the threaded shank 8 of the aw 7 passes, while a nut 10 is screwed on the said shank 8 and is arranged in contacting engagement with one of the sides of the shank 5 of the jaw 6. j

The improvement may be easily and quickly attached to an I-beam and will effectively sustain the bell and jaws 3 thereon. The improvement likewise may be readily detached, and it is thought that the foregoing description, when taken in connection with the drawings will fully set forth the advantages of the improvement to those pkilled in the art to which this invention reates.

Having described the invention, I claim In combination with an I-beam, of a means for supporting a trolley wire therefrom, including a hook to engage one side of the lower flange of the I-beam, said hook having a rightangular flattened shank merging into afthreaded portion and which shank is disposed directly below-the center of the I-beam, a second hook to engage the second side of the lower flange of the I-beam having a depending portion terminating in an angularly threaded extension that passes through the flattened shank of the first men tioned hook, a nut screwed on said threaded extension for clamping the jaws on the lower flange of the Ibeam, and means on the threaded extension of the flattened shank of the first mentioned jaw for clamping a trolley wire thereto.

In testimony whereof I aflix my-signature.
